I had been wanting to wax my Romanian rucksack, my mix was equal parts beeswax paraffin and coconut oil. Using a double boiler and heat gun the mixture one on easily and was soaked up by the old canvas and leather. This is my go-to rucksack here in Costa Rica and I really wanted to make it a bit more water repellent. I'll let it dry for a couple days and check to see if there were any spots that I missed, except for the back panel which I left untreated.
